The ARIA Top 100, an acronym for Accessible Rich Internet Applications, is a set of attributes that extend HTML to make web content more accessible to people with disabilities. It's crucial for web developers to understand and implement ARIA roles, properties, and states to create a better user experience for everyone. Let's delve into the top 10 ARIA roles and states that can significantly enhance your web application's accessibility.

ARIA roles and states help assistive technologies, like screen readers, understand the purpose and state of various elements on a web page. By using ARIA, developers can provide additional information about the functionality and behavior of an element, making the content more accessible to users with visual, auditory, physical, speech, cognitive, and neurological disabilities.

ARIA Roles: Enhancing Semantics
ARIA roles help define the semantic structure of a web page, providing more context to assistive technologies. They are typically used with native HTML elements to provide additional information about the element's role or purpose.

Here are two essential ARIA roles and their applications:
role="button"

The `role="button"` attribute indicates that an element functions as a button. This is particularly useful when creating custom buttons using non-button HTML elements, like a `
Example: `
role=" tablist"

The `role="tablist"` attribute defines a list of tabs. It's commonly used with `
- ` and `
- ` elements to create accessible tab lists.
Example: `
- ...
`

ARIA States and Properties: Providing Context
ARIA states and properties provide additional information about the state or properties of an element, helping assistive technologies understand the current status or behavior of the element.


















Let's explore two crucial ARIA states and properties:
aria-expanded
The `aria-expanded` property indicates whether the element is currently expanded or collapsed. It's typically used with `
Example: ``
aria-current
The `aria-current` property indicates the current page, step, or option of a process. It helps users understand their location within a set of pages or steps.
Example: `Home`
Implementing ARIA roles, states, and properties correctly can greatly improve the accessibility of your web application. However, it's essential to remember that ARIA is not a replacement for proper semantic HTML. It's a supplement that should be used judiciously to enhance accessibility.
To ensure your ARIA implementation is effective, always test your application with assistive technologies and gather feedback from users with disabilities. This will help you create a more inclusive and user-friendly web experience for everyone.
